Rio de Janeiro's favelas sit under near-constant gunfire, and this film gets embedded access to BOPE, the Rio Military Police Special Forces Battalion, as they run raids into territory controlled by heavily armed drug gangs. Their approach is described bluntly by the officers themselves: strike fast, strike hard, and accept that lives on both sides are at risk. The film revisits the Jacarezinho raid of May 2021, when a drug bust turned into a gunfight that left 28 dead, as a case study in how quickly these operations escalate. Interviews with residents describe bullets passing through the walls of their homes, and hospital scenes show emergency doctors treating gunshot wounds they compare to battlefield injuries, with an estimated three people a day killed by stray fire across the city. Beyond the police operations, the film tracks how rival gangs fight each other for territory, leaving ordinary residents caught in crossfire from multiple directions. The contrast the film keeps returning to is the one between Rio's tourist image, Copacabana, samba, Christ the Redeemer, and this daily reality a few miles away.
